' Beit known'that 1 CHARLES GRANDIsoN CHAMBERLAIN, a citizen of the United States, residing at Pacific Grove, in the county of Monterey and State of California, have inv vented anew and useful. Rail-Fastener, of

which the following isa specification.

This invention relates to animprovement in railway chairs or fasteners,A and hasrfor its 'object to provide a simple and efficient cont struction or"- .rail-chair-Whicli'is capable of embracing' the base-flange of Vthe' rail upon both sides, `and Valso bearing against the opv-posite sidesof -the web, whereby the rail is. rmly clamped and supported and'edectively chair being further proyided With elongated .openings or slots arranged opposite tothe inwardly-extending points of said lugs and in line with 4the opposite edges of the base of 'the rail when in operative position, said slots being ad'aptedto receive tapering spikes, which, when driven into place, will serve to swing thech-air sufliciently to cause the saine to stillv more Afirmly clamp the bas-cof the-rail.

Y In the accompanying drawings, Figure l is a perspectiyeyiew `of a railway chair or fas.

Similar numeralsgof reference designate corresponding parts in the several figures of y the drawings.

' Considerable dliculty has been experienced c inthe use'of 'rail-chairs, as heretoforeconstructed-in thatas they are slipped loosely on'the end ofthe' .rail more or less motion or 4 sage of trains.

Fig. 4 yis, a plan. yiew'of a portion of road-bed with my improved chair applied. Fig. 5 is a' d etail per-l spective yvieW'of one 'of the improved coup-l ,Figz 3. -in shape according to the particular shape or Weight of the rail to be used in the construci play is permitted betiveeirtlie rail and the chair, which has given rise to the disagreeableand continuous rattling during the p as-v f By means of this `invention all' motion or .play between the rail and chair is effectively overcome by reason of the chair closely embracing and clamping the bottom j edges and upper face of the base of .the rail. The improved chair, Whichj will now be described, also serves as a caused by centrifugal force on curves or lateral motion on straight lines, by clamping the base of the rail on bothy sides and by arranging the points of thorough brace against anytendency to overturn the rail,

65 the lugs so that. they willv reach Well up and bear againstthe -Webof the rail upon opposite sides.

Referring to the accompanying drawings, I the improved rail-chair comprises a substanl-7o tially flat base or bearing plate l, Whichis interposed betweenthe base of the rail and the :upper face of the tie and'serves as an ef' fective support for the rail, preventing the latter from .Wearing into a Wooden tie. The base lis provided with apairof 'upwardly and inwardly'projecting lugs 2,Which are arranged 2 arearranged in the plane of the opposite side edges' of the base l, and the inner adjacent edges of said lugs lare in clined parallel rel ation,thereby forming an oblique or diagonal recess or space of `a width'suflicient and extend in at or near the opposite side edges` of the base and are therefore diagonally disposed, as shown. The outer opposite faces of the lugs to receive the base of the rail'when the chairl .is turned into such-position as tob'ri'ng. said obl-ique or diagonal recess into alignmentwith 'the base of the rail.

. -It is tobe understood that-the lugs 2 are formed in such manner that their bearingfaces will correspond exactly to the shape of the base of the rail and so that the points of said lugs Will bear snugly against and iirnily support the web of the rail, as indicated in For this reason said lugs are varied posed and are located one opposite the point IOO parent that the improved chair is piace'd in f The slots bring the lugstnereof into engagement with said rail, a pair of these tapering spikes are' inserted into and driven downward through the slots 3, the effect of which is to still iurther swing the chair and cause .the lugs thereof t0 bind against the base and web of the rail. caused by the tapering sides of the s ikes bearing against the edges of the baseo the rail and the outer walls or ends ofthe. slots. or openings 3. When the spikes have been driven home, the heads thereof will engage V-the-base-anges of the rail, thereby assisting in anchoring the rail 'and serving to effectu- -ally preventthe chair'froin turning in a manner that will be readily understood.

From. the foregoing description it will be apposition by introducing the same between adjacent ties and beneath the rail with the oblique or diagonal recess between the lugs in line with said rail, and lowering the rail until V- it rests upon the dat base of thechairl l.. The

. withstanding manytirnes over. Vthese chairs the ties are also protected from chair is then turned until the lugs thereof closely embrace and bindagainst the base and web of therail, after which the tapering spikes are driven home in the manner above del scribed. It will be apparent that as the train passes over the rails, the weight thereof is thrown upon saidv chairs and serves to hold them in place. There is consequently no vertical strain on the spikes asin the usual construction, the strain being in a lateral direction, which the spikes are perfectly capable of cutting by the rails and will last considerably longer as a resu It is to be understood,also, that the chairs ay be made in rights and lefts,

as illustrated in Fig. 4, and'these may be'all ternated or arranged in any manner which is found by practice to be the most serviceable.

5 designates a coupling-plate intended as a substitute for the ordinary ish-plate. This plate is formed from sheet iron or steel, and is It will be understood that this is By the use of made of a length greatcrthan the distance between two adjacent lies, so as to slightly over,- lap the latter. The plate 5 is provided with two spurs or proj eciions 6, one nea r each end, formed integrally therewith and adapted to engage notches formed in the underside of the lhead of the rails,as shown. Two of such coupling-plates 5 are employed at the meeting ends of adjacent rails, as shown in Fig. it, said plates conforming in shape to the head, web, an d base ci .the so as to iit snugly against the same. lt will be understood, that by reason pi.' the spurs or projections G engaging` positively with the notched ends of the rails,

when the chairs l are applied and brought to bear against the coupling-plates, the latter are'held as effectually as if bolted to 'the rail and are not so liable to get loose. These plates may be manufactured' at very low cost and are more. easily applied than the ordinaryv fishplates.

lt willl be apparent changes in the-town and proportion of the base and diagenaliadasposed lugs and in the exact lengthvand location of the elongated openings lor slots, and

the minor details of construction may be reavpair of elongated openings or slots also diagonally disposed and arranged ne opposite' each lug and ii. line with the opposite edges of the base of therail, said openings or slots being extended beneath the base of the rail and adapted to `receive tapering spikes Where# by the driving of a spike will serve totightly' lock the rail within the chair, substantially as described.

IOO r In testimony that I claim the foregoing as my own I havehereto affixed my signature in the presence of two witnesses. 'A CHARLES GRANDESON CHAMBERLAIN.
